  • BSV Webinar 0006: Helicity Space

    Helicity Space CEO Dr. Stephane Lintner, Chairman Jeff Neuman, COO Marta Calvo, and CTO Dr. Set You, discuss the magneto-inertial fusion Helicity Drive with Balerion Advisor Doug McAdams.

    Helicity scientist Seth Pree is on the right running the recording. This webinar was preceded by a tour of the Helicity lab spaces which include a functioning non-nuclear prototype. Following the webinar, we toured NASA Jet Propulsion Laboratory at the California Institute of Technology which is slated to build the upcoming nuclear prototype with Helicity.

    00:00 – 01:30 Welcome & introductions

    Doug McAdams opens the webinar from Pasadena and introduces the Helicity Space leadership team: CEO Dr. Stéphane Lintner, Chairman Jeff Neuman, COO Marta Calvo, and later CTO Dr. Set Yu.

    01:30 – 03:00 Founders’ backgrounds & company origins

    Stéphane discusses his background spanning Caltech science, JPL projects, and Wall Street banking, explaining how Helicity combines technical rigor with disciplined company-building.

    03:00 – 04:30 Why propulsion is the real space bottleneck

    Doug frames the problem: chemical rockets get you to orbit, but deep-space missions are constrained by the rocket equation, thrust-efficiency tradeoffs, and fuel mass.

    04:30 – 06:00 Why fusion propulsion is inevitable

    Helicity explains why fusion has always been the theoretical solution for deep-space travel, referencing decades of physics and popular science visions (Star Trek, The Expanse).

    06:00 – 07:45 Introducing Helicity’s fusion breakthrough

    The team introduces Helicity’s novel fusion propulsion concept and credits the foundational scientific work of Dr. Set Yu, whose plasma physics research underpins the system.

    07:45 – 09:30 Dr. Set Yu’s background & scientific journey

    Dr. Yu outlines his path through Imperial College, Caltech, the University of Tokyo, and the University of Washington, culminating in a DOE Early Career Award and the invention of a novel plasma gun.

    09:30 – 11:30 Why fusion in space is easier than fusion on Earth

    Key insight: space propulsion does not require continuous, wall-plug-efficient power generation—only momentum—making fusion viable earlier in space than on Earth.

    11:30 – 12:45 Pulse fusion vs steady-state fusion

    Explanation of why intermittent fusion pulses are useless for terrestrial power but extremely valuable for propulsion, orbital maneuvering, and spacecraft acceleration.

    12:45 – 15:15 Magneto-Inertial Fusion explained

    Dr. Yu explains Helicity’s approach: an intermediate “Goldilocks” regime between magnetic confinement (tokamaks) and inertial confinement (lasers), balancing density, confinement time, and system size.

    15:15 – 16:45 What makes Helicity’s approach unique

    Two differentiators:

    * Magnetic reconnection heating to preheat plasma efficiently

    * Modular, multi-jet scalability—like adding cylinders to an engine—avoiding material limits of single-source systems

    16:45 – 18:30 Near-Earth and cislunar applications

    Helicity’s drive enables continuous acceleration for heavy cargo transport, orbital logistics, refueling infrastructure, and national security applications.

    18:30 – 20:00 Lunar logistics without launch windows

    Fusion propulsion allows flexible, on-demand Earth-Moon transport, avoiding orbital timing constraints and drastically reducing fuel requirements.

    20:00 – 21:30 Mars missions: speed, safety, and radiation

    Comparison to Starship’s ~9-month Mars transit: Helicity enables ~2-month trips with abort capability, dramatically reducing radiation exposure and mission risk.

    21:30 – 22:45 Science missions & asteroid exploration

    Fusion propulsion shortens mission timelines (e.g., Psyche-like missions from years to months), lowering costs, accelerating science, and enabling sample return at scale.

    22:45 – 24:30 Commercial traction & investor interest

    Helicity discusses backing from venture investors, collaboration with Caltech and JPL, and strong interest driven by real experimental results—not theory alone.

    24:30 – 26:00 Development roadmap & funding strategy

    A staged, capital-efficient plan:

    * Proof-of-concept achieved (~1M° plasma)

    * Scale to 10M° and fusion conditions

    * Modular expansion to net gain

    * First fusion drive demonstrated in space within ~9 years

    26:00 Closing remarks & invitation

    The team emphasizes disciplined de-risking, government collaboration (NASA, DOE, DoD), and invites qualified partners to engage further, while noting appropriate security sensitivities.

  • BSV Webinar 0004: Pulsar Fusion

    Pulsar CEO, Richard Dinan, sits down with Balerion Advisor, Doug McAdams, to discuss next-generation nuclear fusion propulsion systems, including their latest Sunbird design August 22, 2025.

    00:00 Introductions & ContextDoug McAdams introduces Pulsar and CEO Richard Dinan, framing the discussion around fusion propulsion, deep-space logistics, and the limits of chemical and electric propulsion.

    02:30 Richard Dinan’s Background & Pulsar’s Origin StoryDinan discusses his background, the founding of Pulsar, and the motivation for pursuing fusion-based propulsion rather than incremental improvements on existing systems.

    06:00 Why Fusion for Space (Not Earth First)A discussion on why fusion propulsion makes more sense in space than terrestrial power generation, including constraints around mass, efficiency, and continuous acceleration.

    10:30 Overview of Pulsar’s Fusion Propulsion ArchitectureHigh-level explanation of Pulsar’s approach to fusion propulsion and how it differs from tokamaks, inertial confinement, and other terrestrial fusion efforts.

    15:00 Introducing Sunbird: Orbital Tug for Deep SpaceDinan introduces the Sunbird concept — a fusion-powered spacecraft designed to rendezvous with payloads in orbit and dramatically reduce transit times to Mars and beyond.

    20:00 Mission Profiles: Mars, Asteroids, and BeyondHow Sunbird changes mission planning: faster transit times, flexible launch windows, abort capability, and reduced radiation exposure for crewed missions.

    25:30 Comparing Fusion Propulsion to NEP and NTPClear comparison between fusion propulsion, nuclear electric propulsion (NEP), and nuclear thermal propulsion (NTP), including where each makes sense.

    31:00 National Security & Dual-Use ApplicationsDiscussion of strategic and defense implications: rapid orbital maneuvering, logistics, cislunar operations, and geopolitical relevance.

    36:30 Development Roadmap & Technical MilestonesPulsar’s phased development plan, near-term demonstrations, and how the company is de-risking fusion propulsion incrementally.

    41:00 Capital Strategy & PartnershipsHow Pulsar thinks about funding, government partnerships, and aligning long-cycle deep-tech development with realistic capital formation.

    46:00 The Long-Term Vision: Opening the Solar SystemFusion propulsion as a civilizational technology — enabling sustained human and industrial activity throughout the solar system.

    50:30 Closing Thoughts & Final Q&AFinal reflections on timelines, risks, and why fusion propulsion represents a step-change rather than an optimization.
